Hepatitis A is a liver disease caused by the hepatitis A virus. Hepatitis A can affect anyone. In Oregon, hepatitis A can occur in situations ranging from isolated cases of disease to widespread outbreaks.

Good personal hygiene and proper sanitation can help prevent hepatitis A. Vaccines are also available for long-term prevention of hepatitis A virus infection in persons 2 years of age and older. Immune globulin is available for short-term prevention of hepatitis A virus infection in individuals of all ages.

Although the number of cases among Oregonians is at a record low, most cases currently reported are acquired by venturing outside of Oregon to areas having poor practices relating to personal hygiene and environmental sanitation. Such persons placing themselves at elevated risk should seriously consider getting a hepatitis A vaccination at least two months prior to departure.
